Re: [Chicken-users] A couple of questions

[Dan Leslie]

Bare in mind that both lush and fluxus are FOSS, both GPL, so if you're 
planning on using it in a game engine that you'll be monetizing be 
certain that you're abiding by their licenses. Likely this means 
distributing full source.

If that's not desirable to you, might I suggest the SDL egg (LGPL, so 
you can dynamically link proprietary code), or the Allegro egg (BSD). I 
think there's an SFML egg floating around, but I'm not certain where 
it's at these days. Of course, there's also the doodle egg, and 
simple-graphics; and you can always write inline C with the inline, bind 
and foreign eggs.

If you're building binaries with chicken you can opt to statically link 
everything, and you can ship the extension eggs as dynamic libraries 
alongside your binary, if you so wish.
